A legendary henchman of the 1980's who often made appearences in the highly acclaimed TV series, 'Teenage Mutant Ninja Turtles'.
After a mutagenic ooze incident with a rhinocerous in 1983, half man/half animal, RockSteady, found employment under shredder in his brutal reign of terror and crime on the dirty streets of New York.
What he lacked in IQ he made up for in strength and aggression and was rarely seen apart from best pal Bepop(Half Warthog). Underpaid and badly rewarded, together they worked to carry out Shredder and Krangs evil masterplan, often all too easily foiled by the Mutant Ninja Turtles.
In retrospect many look back on the pair as a misunderstood and misguided duo who were manipulated by the much cleverer and meaner Shredder and Krang. Suffice it to say however, the NYPD did not feel the same way.
From 1992 until 1999 RockSteady was incarcerated in Attica Correctional Facility for his involvement in Shredders crimes and in 1997 he was placed on the New York State Local Correctional Suicide Prevention Crisis Service Program for 8 months amid fear he may take his own life.
Since his release he has reunited with Bepop and started afresh creating a new Reggae band who perform in Bars and clubs around the East Coast. Some may go as far to say, he defined the era.

"Is that Rhino or a man?"
"No, thats Rocksteady"
"Oh shit Rocksteady and Bepop have kidnapped April again"
"Yo, rocksteady, look over there." - 'Whack' (Donatello hits rockstead over the head with brick)
"Is Rocksteady dropping those sick reggae beats in Downtown now?"
"Yeh Man, they are sick"

A slower, mellower, yet jumpier style of ska which would later evolve into the Jamaican style of Reggae. Many ska and reggae bands encorporate rocksteady into their music, such as Hepcat, The Slackers, Toots and the Maytals, and even some of the forerunners of ska like the Skatalites. The term "Rocksteady" was coined by Alton Ellis, in the Jamaican summer of '64, the hottest jamaican summer in history, in which it was far too hot to dance to fast ska.

"I like the laid back style of reggae, but I like the jumpiness and energy of rocksteady even better."
